Can skin prick testing needles ever be reused during an allergy test?

As a rule of thumb, a needle must never be reused. After each prick or scratch of the skin, the needle(s) need to be safely discarded. Never place a used needle back into an allergen well. Wiping off a needle between uses is ineffective at removing germs, increases the likelihood of a needlestick injury and can negatively impact the accuracy of testing.
